TENSA-TD
TENSA TD Series UPS
A low-frequency online UPS from 3 to 500 kVA, with an output isolation transformer and DSP digital control. It keeps laboratory instruments running where the mains supply is unreliable, and its status can be monitored remotely through a mobile app.
Key Features
- Unreliable mains power: Keeps supplying the load when the mains voltage is too high or too low, or when there are surges, harmonic distortion or frequency swings
- Load protection: Transfers to bypass on overload, with dedicated short-circuit protection
- Remote monitoring: Input and output data, load condition and battery voltage can be monitored in real time through a mobile app; one terminal covers up to 256 UPS units
